A strict new policy at UC San Diego bans tobacco use anywhere on the campus, even outdoors. That means smoking is prohibited on the university’s more than 2,100 acres and Chancellor Pradeep Khosla, a smoker, won’t be allowed to light up at his soon-to-be official residence — a blufftop mansion in La Jolla that’s undergoing renovations.

Starting last Sunday, the school outlawed use of all tobacco and unregulated nicotine products, such as e-cigarettes. The affected areas include outdoor spaces, parking lots and residence halls. The policy also snuffs out the sale and advertising of tobacco merchandise.

Students will face the new restrictions when they arrive on campus for the fall quarter, which begins Sept. 26. The school previously banned smoking inside buildings or within 20 to 25 feet of them.

The University of California San Diego launch of the sweeping new measure comes four months before the entire 10-campus UC system is scheduled to roll out the same rules. Smoking has been prohibited at UC medical centers since 2011.

The La Jolla campus is the second in the UC system to carry out the tobacco ban; the UCLA one took effect in April. The UC will be the first statewide college system in California to forbid all tobacco use, said education and public-health officials.

UC San Diego joins more than 1,180 college campuses nationwide that have adopted smoke-free policies. Of those, 798 also have imposed tobacco-free rules, according to Americans for Nonsmokers’ Rights, a nonprofit lobbying organization based in Berkeley.

In San Diego County, Point Loma Nazarene University also bans smoking on its campus as do most of the community colleges, said Debra Kelley, regional director for programs and advocacy with the American Lung Association.

San Diego State University, California State University San Marcos and Southwestern College allow smoking in designated outdoor locations, although the SDSU University Senate has voted in favor of a completely smoke-free campus.

Kelley said students at the University of San Diego recently contacted her group to express interest in making their campus smoke-free as well.

At UC San Diego, violators will be given cards that outline the rules and provide information about smoking-cessation services, including the toll-free California Smoker’s Helpline that operates out of the university — (800) 662-8887. In addition, the student center will hand out free “quit kits” and starter packs of nicotine replacement therapy.

People who aren’t interested in quitting can use nicotine patches, gum and other products to manage symptoms while on campus, said Karen Calfas, the university’s executive director of student health and well-being,

“The idea of this policy was not to be punitive toward smokers but to move to a healthier environment,” she said. “We are approaching this as a transition. It will take people a while to get used to the policy, and the intention is to help people adjusting to the policy.”

Although the enforcement strategy emphasizes education, state law does allow campus police to cite violators and charge them a fee.

Calfas played a key role in the UC smoke-free movement, including writing a proposed policy on behalf of a systemwide committee. In January 2012, then UC President Mark Yudof gave the system’s campuses two years to implement the ban.
